DEVICE FOR LOCATING FLUID LEAKAGE

PROBLEM TO BE SOLVED: To provide a device for locating a fluid leakage capable of reducing a recognition error on the starting time of leakage sound due to noise, more accurately locating a fluid leakage, and being produced at a low cost due to a simple constitution. SOLUTION: In the device 1 for locating a fluid leakage, acoustic sensors 10a and 10b are mounted on a fluid housing body 100 such as a conduit in at least two locations, and a leakage location X is oriented by the difference between the starting times of intermittent leakage sound in reception signals of channels CH1 and CH2 each detected by the acoustic sensors 10a and 10b. In the case that a reception signal at each channel continuously exceeds a threshold for more than a predetermined time in the vicinity of the trigger time in which a reception signal at least at one channel CH1 exceeds a threshold, the first time of the continuation is taken as the starting time of each channel. Reception signals are each sampled only for predetermined sampling time from the time returned to the past from the trigger time by pre-trigger time, and each starting time is obtained through the use of the sampled reception signals of each channel.
